Hello Friend how are you? your posts put me to investigate and learn new things, I did not know of these coins just for collection, this physical version of the cryptocurrency has double value: as currency and as a work of art.
No other can be more appreciated among collectors than the creations of Kialara, because each case is collectible and has beauty on its own.
They are very beautiful in my opinion the purpose of owning physical bitcoins varies, while some use metal coins for their market value, others want to own them as a real piece that represents a part of the history of technology. Thanks for this valuable information, the images are beautiful

Greetings from Venezuela!
